Michigan

I'm a new member from Michigan. A friend of mine has recently introduced me to long range target shooting and I fell in love with it. I've currently got a Remington 700 in .270 win that groups around 3.5" at 400 yards but this summer I'm looking to build a .300 win mag for 1000+ off a Winchester model 70 I've inherited. I've found a lot of good information on this forum so far and hope to be able to contribute my 2 cents as well in the future. Thank you.
